GreenLight Biosciences Pioneers RNAi Herbicides: A Non-GMO Revolution in Weed Control 05-08-2025

Summary :

Agricultural biotech firm GreenLight Biosciences has achieved a breakthrough in RNA-based herbicide development, expanding its portfolio to non-GMO weed management. Trials confirm sustained efficacy, enabling synergistic use with herbicides to reduce toxicity and costs. The company aims to deploy RNAi solutions for resistant weeds, starting with glyphosate-resistant horseweed, and is preparing global regulatory submissions. The innovation addresses a $10B/year resistance crisis and aligns with sustainable agriculture goals.


Agricultural biotechnology firm GreenLight Biosciences, a leader in leveraging RNA-based platforms for next-generation crop protection, has announced a transformative breakthrough in its herbicide development pipeline. This milestone expands the company’s portfolio beyond insect pest control into integrated weed management solutions, offering non-transgenic (non-GMO) alternatives designed to enhance crop resilience against heat stress and bolster plant defense mechanisms.


Validation Through Rigorous Testing: Synergistic Efficacy and Environmental Stewardship

Extensive greenhouse and field trials have demonstrated consistent, long-lasting herbicidal activity using GreenLight’s proprietary RNA interference (RNAi) technology. The results underscore the platform’s capacity to control recalcitrant weed species while enabling synergistic use with conventional herbicides. This dual-action approach amplifies efficacy, reduces overall chemical toxicity, and minimizes application volumes—a trifecta that lowers input costs for farmers and simplifies integration into existing weed management strategies.

The companys strategic roadmap aims to deploy a suite of RNA-based solutions tailored for row crops and specialty crops, addressing a spectrum of economically damaging weeds. By targeting herbs at the molecular level, these innovations promise to mitigate ecological risks associated with traditional pesticides and curb the proliferation of herbicide resistance, a growing global challenge costing U.S. agriculture an estimated $10 billion annually in yield losses.


Pipeline Spotlight: Precision Targeting of Conyza canadensis (Horseweed) in No-Till Systems

At the forefront of GreenLight’s pipeline is a lead candidate engineered to combat Conyza canadensis (horseweed), a notorious weed in no-till soybean production systems. Leveraging deep biological expertise and AI-driven design algorithms, the company screened over 180 potential candidates to select this lead molecule. Horseweed’s resistance to glyphosate and other herbicides has rendered it a critical management challenge, particularly in conservation tillage practices.


Executive Insight: Revolutionizing Weed Control with RNAi Precision

Our RNA-based platform introduces a paradigm shift in non-GMO weed management,” said Andrey Zarur, CEO of GreenLight Biosciences. “By enabling precise, target-specific control, this technology reduces reliance on legacy chemical herbicides like glyphosate, offering farmers a sustainable alternative to combat resistant weeds.”


Market Context: A Gap in Innovation Amid Rising Herbicide Use

Herbicides constitute the largest segment of global crop protection products, with usage surging by over 44% between 2017 and 2022. Despite substantial R&D investments, only one novel herbicide mode of action has reached commercialization in the past three decades, leaving farmers with limited tools to combat resistance. GreenLight’s RNAi approach introduces a distinct mechanism of action that complements, rather than competes with, biological pathways, offering a non-disruptive solution to this challenge.


Technological Edge: RNAi Foliar Sprays for On-Demand Weed Suppression

GreenLight’s RNAi foliar sprays are engineered to disrupt essential weed functions without harming crops or non-target organisms. RNA molecules degrade rapidly post-application, ensuring efficacy while eliminating persistent residues—a critical advantage for growers seeking alternatives to chemical-intensive practices. This targeted disruption provides a much-needed tool to manage resistant weeds and reduce the environmental footprint of agriculture.


Regulatory and Commercial Trajectory: Accelerating Global Access

With these advancements, GreenLight Biosciences is preparing regulatory dossiers to facilitate market entry across key agricultural regions. The company’s commercialization strategy builds on recent successes, including the 2024 EPA and state registrations of Calantha™, an RNAi-based solution targeting the devastating Colorado potato beetle (Leptinotarsa decemlineata), a primary pest of solanaceous crops. Additionally, the company submitted its Varroa mite control product for EPA review in early 2023, addressing a critical threat to honeybee populations.


Conclusion: Bridging Innovation and Sustainability in Agriculture

GreenLight Biosciences’ RNA-based pipeline exemplifies the convergence of biotechnology, AI-driven discovery, and environmental stewardship. By offering farmers precise, low-toxicity tools to manage weeds and pests, the company aims to redefine sustainable agriculture while reducing the economic and ecological burdens of conventional chemical inputs. As regulatory pathways progress, these innovations could herald a new era in crop protection, aligning productivity goals with planetary health.
